I am about to publish a 2nd paid app and am a little unsure how to go about licensing and [basic] piracy protection.<p>With my first app I made it very restrictive - a failed lvl query resulted in the app not working. Unfortunately the amount of false positives has been considerable, but I had the luxury of being able to make old versions of the app obsolete with updates and trying various things over time.<p>The new app is going to be much more casual/simple, so I'd like to avoid any strict lockdowns. Its also not dependent on anything else, once its out, its out.<p>I'm wondering if anyone here has some experiences to share as far as handling failed purchase checks. The goal to is to deter the most causal of pirates - nothing fancy.
